Most of you may think of clams(河蚌) as part of delicious food. But these little things can do an important job: testing(测试) the cleanliness of water in nature and people’s drinking water.
The important water plant in Warsaw, Poland, gives water to its people there. It uses eight clams to help test the water every day.
Clams can find very small changes quickly in water. If the water is not very clean, the clams will close their shells(壳). People in the water station connect(连接) their shells to a computer. When four or more clams close their shells at the same time, the workers can get a tip(提示) from the computer quickly.
To make the clams always find very small changes quickly in water, the workers choose some new ones to work for them every three months. “It works well and it helps save people’s drinking water, rivers and lakes,” the worker in the water station said.
